ram doesn't work on upduino v2

[roman65536]

Hi,
after little bit of fiddling, I was able to run hallo world on upduino v2 from flash.
However it look like nothing which was written to ram, came the same when read from the same memory location. Any subroutine call end in hanging the cpu. I can't figure out why.

thank you
Roman

I suspect, there is something with the tools, that's way ram is not working correctly. Would somebody write, what version of tools the code is running without problem ?

@roman65536 , are you able to share what fiddling you did? I tried this on my UPduino and I get nothing on my console...
I have heard that the RAM on the ice40 requires more time to settle after power up. Perhaps the reset needs to be extended?

No, I switched to picosoc. They use the internal 128kB ram, which is anyway better then icicle. rgdsRoman On Thursday, September 17, 2020, 5:58:14 PM GMT+2, vr2045 <[email protected]> wrote: @roman65536 , are you able to share what fiddling you did?
